Description

Technical Field

[0001] This utility model relates to the field of perforating gun technology, specifically a perforating gun section that is easy to install. Background Technology

[0002] A perforating gun section is a tubular component used in oil and gas extraction perforation operations to connect various parts of a perforating gun or to achieve specific functions. It is typically a unit within a perforating gun system, possessing a certain length and specific structure. It can be used in conjunction with other components such as the gun head, gun tail, and perforating cartridge to form a complete perforating gun assembly, enabling the perforation of oil and gas well casings or formations, thus establishing a pathway for oil and gas to flow from the formation into the wellbore.

[0003] However, existing perforating gun sections are usually tubular structures with threads at both ends, allowing for threaded connections to the gun head, gun tail, and other components. However, this installation method typically requires the use of wrenches and screwdrivers to complete the installation and disassembly process, leading to inconvenience in installation and disassembly. Therefore, we propose a perforating gun section that is easy to install. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an easy-to-install perforation gun section, solving the problems of inconvenient installation and disassembly.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a short section for a perforating gun that is easy to install, comprising a first outer tube, a sand cap installed at one end of the first outer tube, a connecting rod fixedly connected to one end of the sand cap, a docking rod installed at the other end of the first outer tube, a second outer tube fixedly connected to one end of the docking rod, and a gun head installed at one end of the second outer tube;

[0008] The other end of the sand cap and both ends of the docking rod are fixedly connected to docking frames. The inner side of the docking frame is fixedly connected to a clamping tube. A clamping spring is installed inside the clamping tube. Both ends of the clamping tube are movably connected to clamping beads.

[0009] Both the first outer tube and the second outer tube are equipped with perforation tubes, and the perforation tubes have projectile ports on their outer sides.

[0010] Preferably, one end of the gun head is fixedly connected to a threaded head, which is threadedly connected to the second outer tube.

[0012] Preferably, both the docking bracket and the threaded head have a limiting port at one end, and the limiting port has a square structure.

[0013] Preferably, both ends of the perforating tube are fixedly connected to limit rods, and the outer width of the limit rods is adapted to the inner width of the limit opening.

[0014] Preferably, the perforating tube is made of metal material and has a smooth outer surface.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a short section for a perforating gun that is easy to install, and has the following advantages:

[0017] 1. This utility model, through the design of a locking bead, a connecting bracket, a locking tube, and a locking spring, allows for easy installation of the perforating gun section. The operator inserts the connecting brackets at both ends of the connecting rod into one end of the first and second outer tubes, respectively, aligning the locking bead of the locking tube with the locking slot. Simultaneously, the limiting port at one end of the connecting bracket aligns with the limiting rod. Then, the first and second outer tubes are pressed inwards, and the locking spring pushes the locking bead into the locking slot, completing the installation. Disassembly is simple: just press the locking bead inwards, causing it to compress the locking spring and retract into the locking tube, allowing the first and second outer tubes to be pulled out. Therefore, installation and disassembly can be completed without the need for wrenches or screwdrivers, making it convenient. Attached Figure Description

[0024] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0025] This utility model provides a technical solution:

[0026] Please see Figures 1-4 A short section for a perforating gun that is easy to install includes a first outer tube 1, a sand cap 2 installed at one end of the first outer tube 1, a connecting rod 3 fixedly connected to one end of the sand cap 2, a docking rod 4 installed at the other end of the first outer tube 1, a second outer tube 5 fixedly connected to one end of the docking rod 4, and a gun head 6 installed at one end of the second outer tube 5.

[0027] The other end of the sand cap 2 and both ends of the docking rod 4 are fixedly connected to the docking frame 10. The inner side of the docking frame 10 is fixedly connected to the clamping tube 12. The clamping tube 12 is installed with a clamping spring 1201 inside. The two ends of the clamping tube 12 are movably connected to the clamping beads 9.

[0028] Both the first outer tube 1 and the second outer tube 5 are equipped with perforation tubes 13, and the outer side of the perforation tube 13 is provided with a projectile port 14.

[0029] Furthermore, a threaded head 601 is fixedly connected to one end of the gun head 6, and the threaded head 601 is threadedly connected to the second outer tube 5, so that the gun head 6 and the second outer tube 5 can be firmly fixed together.

[0030] Furthermore, the outer sides of the first outer tube 1 and the second outer tube 5 are respectively provided with a gun muzzle 7 and a bayonet 8. There are eight bayonet 8s, and each pair of bayonet 8s forms a group. The bayonet 8s enable the locking bead 9 to lock in place after insertion.

[0031] Furthermore, a limiting port 11 is provided at one end of both the docking frame 10 and the threaded head 601. The limiting port 11 has a square structure, which enables the limiting port 11 to limit the limiting rod 15. When the limiting rod 15 is inserted into the limiting port 11, it can prevent the limiting rod 15 from rotating.

[0032] Furthermore, both ends of the perforating tube 13 are fixedly connected with limiting rods 15. The outer width of the limiting rod 15 is adapted to the inner width of the limiting port 11. When the limiting rod 15 is inserted into the limiting port 11, it can play a limiting role and prevent the perforating tube 13 from rotating and shifting.

[0033] Furthermore, the perforating tube 13 is made of metal material, and the outer surface of the perforating tube 13 is smooth. The perforating tube 13 made of metal material is more robust and durable and less prone to damage.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] When installing the perforating gun section, the operator loads the ammunition into the firing port 14, and then installs the perforating tube 13 into the first outer tube 1 and the second outer tube 5. At this time, the limiting rod 15 at one end of the perforating tube 13 will be inserted into the limiting port 11, thus playing a limiting role. At the same time, the firing port 14 of the perforating tube 13 is aligned with the muzzle 7 on the outside of the first outer tube 1 and the second outer tube 5. Then, the docking brackets 10 at both ends of the docking rod 4 are inserted into one end of the first outer tube 1 and the second outer tube 5, so that the locking ball 9 of the locking tube 12 is connected with the locking port 8. At the same time, the limiting port 11 at one end of the docking bracket 10 is aligned with the limiting rod 15. Then, the first outer tube 1 and the second outer tube 5 are pressed inward, and the locking spring 1201 pushes the locking ball 9 into the locking port 8 to complete the installation. When disassembling, simply press the locking ball 9 inward, and the locking ball 9 will compress the locking spring 1201 and retract into the locking tube 12. At this time, the first outer tube 1 and the second outer tube 5 can be pulled out to complete the disassembly.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
